我有这个确切的问题。我假设你有一个函数，它定期发出请求到服务器获取数据，然后更新页面，如果因为你提出要求的最后一次数据已经改变。

I've had this exact problem. I'm assuming that you've got a function which periodically makes a request to the server to fetch data then updates the page if that data has changed since the last time you made the request.

Internet Explorer将缓存的Ajax调用的结果，即使你告诉它不要在你的HTTP头相同的资源。所以，如果你犯了一个请求 GET_DATA？ID =什么一遍又一遍，IE浏览器会发出请求一次，然后停止制造它的未来，只是返回的结果第一请求。

Internet Explorer will cache the results of Ajax calls to the same resource even if you tell it not to in your HTTP headers. So if you make a request to get_data?id=whatever over and over again, IE will make the request once and then stop making it in the future and simply return the result of the first request.

的解决方案是一个虚设参数添加到请求字符串。所以，首先你要求 GET_DATA ID =无论＆放大器;？ie_hack = 0 然后 GET_DATA ID =无论＆放大器; ie_hack = 1 等这将阻止IE浏览器缓存的结果，并迫使它使每一次的要求，因为它看到了每个请求一个不同的查询字符串。

The solution is to add a dummy parameter to the request string. So first you request get_data?id=whatever&ie_hack=0 then get_data?id=whatever&ie_hack=1 etc. This will stop IE from caching the results and force it to make the request each time, since it sees a different query string for each request.
